BRAIDING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 521,019, dated June 5,1894. 7

Application filed October 18, 1893. Serial No. 488,552. (No model.)

To all whom it may concern.-

Be it known that I, JAKOB DRNEK, a subject of the Emperor ofAustria-Hungary, residing at Vienna, Austria-Hungary, have invented anew and useful Braiding-Machine, of which the following is aspecification.

This invention relates to anew and useful improvement in braidingmachines, and it consists in the'arrangement and combination of partshereinafter set forth and claimed, whereby the spindle carrying thebobbin or spool is carried positively bya rotating plate instead of asheretofore traveling in a circular track.

The invention is illustrated in the accompanying drawings, wherein--Figure 1 is a longitudinal section of the machine taken on the line w-w,Fig. 5. Fig.

,2 is a transverse section of the machine taken on the line y-y Fig. 5.Fig. 3 is aplan view of the machine sectioned on the line zz Fig. 1.Fig. 3 is a transverse section taken on the line y-y Fig. Fig. 4 is aplan view of the machine sectioned on the line 12-11 Fig. 1. Fig. 5 is atop plan view of the entire machine. Fig. 6 is an underneath view of theribbon holder or spindle. Fig. 6 is a top plan view. Fig. 6 isa sideelevation and Fig. 6 an end view of saidbobbin holder.

Fig. 7 is a side elevation of the machine and.

of one form of braid woven thereby and Fig. 8 is a diagrammatic view ofthe course taken by the bobbins during the operation of weaving in amachine of the form illustrated.

Upon a suitable bed plate 1 is secured the casing 2 the inner wall orperiphery2 of the 1 same being substantially 8 or incising circularshaped. Within the center of each half of this casing 2 are placed twoshafts 7-7-, one of which 7 is a continuation of the power shaft 4.. Thepower shaft has a bearing in the bed plate 1 (being supported by thecollars 3, 3) while the shaft 7 is firmly secured to and supported onthe bed plate 1 by means of the collar 3 and nut 3 Firmly secured to theshaft 7 is ,a gear wheel and plate 9, secured together by a sleeve 8.One form of securing the gear 5 and plate 2 to the shaft is shown inFig. 1 wherein the same is ac complished by means of a set screw 8*passing through the sleeve 8. The gear wheel 5 meshes with acorresponding gear wheel 6 of exact diameter and of the same number of Ishafts 7 and 7 are substantially conical by preference and the plate andgear wheel on each shaft is held down in place between the collars 11and 3. The peripheries of the plates 9 are beveled in oppositedirections as at 9 so that they overlap directly in the center of themachine (see Figs. 1 and 3). At certain regular predetermined points inthe circumference of eachplate 9 are cut semicircular slots or recesses10 shown in the drawings to be three in number in each plate. Theseslots 10 are approximately the same in width as the diameter of theshaft 12 of the bobbin holderD. This shaft 12 is clamped in the slot 10by the square collars or plates" 13 which fit on the upper and lowersurfaces of the plate 9. Two of the sides 13 of the collars 13 arerounded on anarc of a circle corresponding to the circular wall 2 ofcasing 2. The recesses 10 are cut to such a depth and the distancesbetween the curved sides of plate 13 are such that when the shaft 12 ofbobbin holder D is in said recess, one of the curved sides 13 of saidplates 13 will slide over the curved wall 2, which wall 2 acts as abearing therefor. The lower of the two sleeves 13 carries on its undersurface a rail 17 extending across the sleeve 13 from one flat side tothe other and directly in the center of saidsleeve (see Figs. 6 and 6).Between the plates 9 and the gear wheels 5, 6 and at equal distancesfrom each of the sleeves 8 is placed a plate 15 substantially as shownin Fig. 2 andhaving formed in its 11pper surface two diagonal grooves 16crossing each other at the center of the machine and adapted to receiveand guide the rail 17 of the bobbin holder. The upper end of the holderD is furnished with a shaft 14 (conical by preference) upon which thespool or bobbin Sp is placed.

In operation power is transmitted from shaft 1 to the shaft 7 whichrotates the plate 9 and the gear wheel 5. This gear wheel 5 rotates thegear 6 and the other plate 9, both plates 9 and gears 5, and 6 travelingwith the same degree of speed. The bobbin holderD too is carried by therecess of one plate 9 around one end of the circular wall 2 until therail 17 reaches the groove 16 in plate when the bobbin holder is shiftedover into engagement with one of the recesses 10 of the other plate 9when that plate carries the bobbin holder around the other end ofthecircular wall 2 until the rail 17 reaches the end of the other groove 16in plate 15, when the bobbin is again shifted into engagement with thefirst plate 9 and the operation continued indefinitely. The path of thebobbin is indicated in diagram in Fig. 8. The course of the otherbobbins or spools is precisely similar to that above described. Wherethe plates 9 are furnished with three engagement points or recesses 10,there may be three bobbins used, which are arranged in such a manner,that they occupy-at certain intervals durmg the operation--the positionshown in Fig. 5. By this arrangement collision between the bobbins isavoided, for in no case can they come in contact with each other at theplate 15, the only point at which they cross. It is manifest that morethan three bobbins may be operated and that more than two plates 9 andgears may be used and that these plates 9 may have more or less thanthree engagement points or recesses 10. The arrangementin the casessupposed above depends simply on mechanical calculation and can readilybe worked out by the skilled mechauic.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- The combination in a braiding machine, of

the revolving shaft 7, a gear wheel 5, beveled plate 9, and sleeve 8secured to said shaft and connecting said gear wheel and beveled platetogether, said beveled plate being recessed at regular intervals in itsperiphery, a stationary shaft 7, a gear 6 meshing with said gear 5 andrevolving on said shaft '7, a second plate 9 beveled in an oppositedirection to the first plate and overlapping the same, a sleeve 8uniting said second plate to said gear 6, a casing 2 surrounding saidplates and substantially 8-shaped, with the stationary switch plate 15,provided with grooves 16 crossing each other midway between said shafts7 and 7, said plate 15 being placed midway between the sleeves 8, andbetween the revolving plates and their gears, andwith a bobbin holder Dcarried by said revolving plates and held in the recesses thereof by thecasing 2, plates 13 secured to said bobbin holder and adapted to rest onthe upper and lower surfaces of said revolving plates, two of the sidesof said plates being cut onan arc of the circle of the casing 2 andadapted to bear thereon until the bobbin holder reaches the plate 15,and with a rail 17, carried by the bobbin holder D andadapted to enterthe grooves 16 of the plate 15 and to guide said bobbin holder thereon,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
